The single-port Cisco Aironet power injectors combine 48-VDC power with the data signal, sending both to the Cisco Aironet access point or bridge.

Cisco Aironet 350 Series access points and bridges include an integrated power supply and injector (AIR-PWRINJ).

The power injector for Cisco Aironet 1100 and 1200 series access points (AIR-PWRINJ3) works with the power supply provided with the access point.
